Comment on In-Script simulation of a load-balancer with LoadRunner by Kim

Kim — Thu, 19 Nov 2009 13:16:08 +0000

The VUserID is obtained from a variable in the Prameter List (in VuGen) defined as a “VUser ID” with format %s.

This ID is then used as the determining factor for the Even or Odd users. Even/Odd is determined using a binary AND operation on the actual VUserID number. If you apply VuserID AND $0001 you will take out only 1 bit, that bit changes between 0 and 1. It also happends to be the bit that changes the most (being the Least Significant Bit (LSB) bit).

In C code the && characters signifies the AND operation. More info at http://www.gamedev.net/reference/articles/article1563.asp

For a more indepth description of the AND operation in general have a look at http://en.wikipedia.org/wiki/Binary_and.

Hi,

Could you please explain how this particular piece of code works?

if (VUserID & 1==0) // use AND operator to filter out LSB bit

Regards,

Webload has parameter to find out the userid parameter in LR. it’s called ThreadNum.
for the user1 – ThreadNum value is 0 and User2 -> ThreadNum is 1

The code is

if(ThreadNum %2 ==0)
{
Base URL 1
)
else
{
Base URL2
}

Hi……

replace(const char *string, char *pattern, char *replace, char *match)
{

int length;
int status;
int eflag;
char buf[1024] = “”;
char out[1024] = “”;

regex_t re;
regmatch_t pmatch[128];
lr_load_dll(“pcre3.dll”);

if((status = regcomp(&re, pattern, REG_EXTENDED)) != 0){
regerror(status, &re, buf, 120);
lr_output_message(“Match PCRE Exit 2″);
return 2;
}

while(status = regexec( &re, string, 1, pmatch, eflag)== 0){
strncat(out, string, pmatch[0].rm_so);
strcat(out, replace);
string += pmatch[0].rm_eo;
eflag = REG_NOTBOL;
}
strcat(out, string);
lr_save_string(out, match);
}

Comment on Using a custom DLL in LoadRunner by brett

meset…brilliant, now why couldn’t have Merccury/HP had that clearly defined in the help? They were telling me to clear the buffer with free(buff); which didn’t work…but that must be for static pointer variables, and not arrays.
